Is the compressor running? Is the coils near the compressor clean and is the fan that blows on the coils running? Does it get cold at all or is it room temp? One thing to do is to turn it on after leaving it unplugged for and hour. First access the compressor and make sure you can feel the copper lines coming out of it. Some have 4 plus a service pigtail. On the ones with 4 will have two lines the same size that circulate oil for cooling the compressor running to a small set of coils. Pay attention to the larger and smaller lines and notice what temperature they feel like before you plug it back in. Once it is plugged in and if the compressor is running less than a minute the small line should get hot, up to 140 degrees F. Check it soon as after a few minutes it can burn you...The largest of the lines is the low side or suction side and it should be very noticeably cooler than room temp and continue to get colder the longer it has been running. If both these things happen, the charge should be adequate, and the compressor is working. I would then check to see if air is circulating in the unit..Are all the fans running when the unit is on? Most common is for the defrost circuit to fail causing the unit to build up ice behind the liner blocking air flow. Unplugging the unit and leaving the doors open over night will let it thaw. Put several towels around the unit incase this is the problem as there will probably have more water come out than the small pan under neath the unit can handle. Once all the water stops dripping out, plug it back in and see if it works correctly. If so it will probably freeze up again and need to be defrosted again. If so the defrost circuit has failed....either the thermostat in that circuit, the heater coils or the defrost timer switch. Switch very common, coils next and the high temp sensor last.... let me know what you find...

How much R22 should my unit hold when fully charged

If it has enough freon to freeze up then its not that low. Normally a 4-5 ton cooling only (non heatpump) will hold 7-9 lbs r-22 or 9-11 r-410a. Freezing can be caused by dirty air entering side of the coil also. Or slow blower

Fridge/freezer not cooling but copper pipe near the compressor freezes up

If freon was needed at all, then your system must have a leak, it is never advised to add freon because of this. If your suction line is freezing up to the compressor shell, you are most likely over charged and the evaporator is flooded/saturated with freon and unable to cool/freeze properly. The freon should be added by weight or volume as noted on the model/serial sticker on the unit only, if the sticker is not present, than an experienced technician will need to charge by temperature/pressure using a set of gauges. Prior to charging, the system needs to be fully evacuated to ensure all non-condensables are removed from the system. Pleazer Appliance...

Wont cool anymore or freeze,used to be able to unplug and it would start working again.Not this time ,the compresser will not come there a sensor to tell it to come on.

If it won't come on then it can't cool or freeze. Was it not freezing before it quit? Not freezing could be low freon and the inside coils may be iced up. This unit may have a bad start capacitor or need a hard start capacitor kit to help it kick on. Empty the freezer and take a look-see behind the removable back panel. Come on back .

Wine cooler too cold, compressor keeps running, temperature display is off

Let me first go over how a sealed system actually works that way when I tell you whats wrong you won't think I'm crazy. There are two sides to the freon system, known as the sealed system. The low side, where freon is in a gas form. In this form, freons temperature is at its coldest. Now, the freon can't just sit because movement is required for it to be cold. The high side does this by compressing the gas into a liquid,which pressure causes the temperature to rise, and forcing it through to the low side where it becomes a gas. So, with that said, the more freon in a sealed system the more pressure is applied, causing a higher temperature because less time as a gas. This is how they make wine coolers, walk in fridges, etc cool, not freeze. If you were to remove freon, the temperarture would get colder. Your wine cooler should have enough freon to prevent this from happening, and it doesn't therefor the freon has more time as a gas. Either you have a leak, or you've somehow knocked a freon line loose. It should have a year warranty on it.

How do I add freon to my ac compressor?

unless you are licensed to handle freon don't. there are some big fines for releasing freon. also if you are not experienced there are safety concerns!!! Is this a home hvac or car? Now with that said you have to add it on the suction side of the compressor.You will need to know the correct type of freon that goes in your unit which can be found on a tag on the unit. You will also need a set of ref. gages to monitor the low and high pressure sides of the unit. it also needs to be added to the outside unit service ports (Home). You need a set of ref scales so you know how much ref is being added. Too much ref and you start pumping liquid. Too little ref and it doesn't cool like it should. If its a car you still need the above equipment. still goes in the suction side.If you add to much ref you can lift the safety pressure valve and dump the freon in the car system. Each type of ref has a pressure you want to see on the suction side and hp side. since they differ with each type ref. you will have to look it up possibly on the internet. If suction pressure goes below 32 degrees you may freeze any condensate the unit makes and have another problem. Hope this helps you but its not as simple as hooking up a ref cylinder and just adding freon. their are many thing that can go wrong and damage equipment or hurt is the first priority.

Model#1051 small dorm size...doesn't matter where i set sill freezes everything,,,suggestions?

Repace thermostat. You didn't tell us that it runs ALL the time. It does. You don't have to tell me, I know it does. The first thing the power does is go thru the thermostat and its job is to turn the power off to the pump when it gets cold enough. If it gets cold and freezes everything then everything else is working right. There is no fixing the old thermostat either. That little tube that looks like a heavy bare wire ending next to the freezer coil has a little "freon" in it that expandes and contrectes with temp. change and the change in pressure is what ativates the thermostat. Chances are the "freon" leaked out.
Note, this is not the same "freon" that is pumped around the fridge to cool things. This is sealed in the thermostat and tube only.

Freezer isn't cold, defrosted all of my food and the refrigerator part doesn't seem very cold either.


If your refrigerator cooling doesn't seem to be working well, and you have no idea what to look for in troubleshooting your problem, there are some things you can do to try to figure out your problem without paying a serviceman to come into your home.

Most new refrigerators come with automatic defrosters. Although this is a standard feature the drain hole in the defrosting assembly can get clogged with debris, lime, or even ice. If this happens the defrost will not work and there will be a build-up of ice in your freezer that begins to block the freon from flowing properly and causing heat to react improperly and cause your refrigerator to stop cooling.

Freon systems in a refrigerator are closed systems but on occasion you may need a recharge. Refrigerators use R-134a freon, just like in an automobile. The old R-12 freon is no longer available, so if you have an older model of refrigerator you will not be able to obtain the freon, and it will be recommended that you replace that refrigerator.

The seals that are on the door of the refrigerator and freezer can dry rot with time. When you begin to see the seals cracking or warping, if your refrigerator opens more easily than before, or if you see the the door does not close fully without pushing on the door then the gaskets around the doors will need to be replaced. They are held in place by clips and the replacement is an easy fix.
Holes in Lines

Let's face it, many people find ice in their freezer or the back of their refrigerator and will try some self-help without knowledge. They will grab a knife or fork and start chipping away at the ice. This is extremely dangerous. There is a great risk of puncturing a hole in the freon lines by stabbing at the ice. Since freon has the purpose of cooling most ice collects the thickest on the inside of the walls with the freon lines right behind the plastics. A better method of removing the ice is to empty your refrigerator, turn it off and leave the door open. If you want to speed up the process you can turn on a blow dryer and aim it at the edges of the ice. If you aim at the edges you will warm up the ice and create warm water which will flow down and help to separate the ice panel from the wall.
Uneven Refrigerator

If a refrigerator is not even on the floor it may not close properly. Rock your refrigerator and see if it seems to topple from one foot to another. The feet on a refrigerator can be adjusted by screwing in or out and leveling each foot individually until they are all even.
Non-Problem Warming

If your home is hot your refrigerator will work harder. If you put a lot of food in your refrigerator and freezer, your coolant will have to work harder, and it will seem to take longer to cool. It is just that there is a lot of food that is trying to freeze or maintain cool temperatures.

Good luck

At a State park... AC freezing up

If the unit is low on freon, there should be visible signs of leaking somewhere in the upper unit. Are you running the system on Low Cool? This will often times cause the AC to freeze up because the condenser fan and the evaporator fan are on the same motor. If you run the system on low cool, you are not getting enough air movement over your condenser to effectively warm up the freon and thus causing the system to freeze. Turn it to high and adjust the thermostat if it is too cold, this should help.

Freezer compartment of refrigerator not freezing

First, I think it’s important to know that the Ref side has no cooling coils, it’s basically a box and the cold air in the freezer is blown over by a fan through a channel into the Ref side. This channel has a door which regulates how much cold air goes through. You probably have two control knobs in the Ref side, one controls the temp with numbers 1-9, 9 being the coldest. This temp control tells the compressor how long to run. The other control is for that little door and it may have letters A-E, E being the coldest. If you set it on E (coldest) then this will close that little door and keep most the cold air in the freezer.
So, how can the Ref side be cold and the freezer side not freezing?

1. Coolant leak. There is enough coolant to keep the Ref side cool but not enough to freeze on the freezer side.

2. Defrost system failure. The coils on the freezer side are clogged with ice and it's just a matter of time when the Ref side won't cool either. The back wall in the freezer will be covered with ice/frost

Jenn Air ref/freezer not freezing/cooling

Take the back out of the freezer and check and see if the refrigerator is in defrost while it is cooling if it is replace the timmer, then check and see if the fan on the underside is working if not replace the motor this will cause the problem also.
If all that is ok feel the small line under the refrigerator ( high side) and see if it is hot while it is running if not check the freon in the refrigerator.
